Magnesium batteries are safe -- unlike traditional lithium ion batteries, they are not flammable or subject to exploding -- but until now their ability to store energy has been limited. Researchers have reported a new design for the battery cathode, drastically increasing the storage capacity and upending conventional wisdom that the magnesium-chloride bond must be broken before inserting magnesium into the host.
